Pinned topicCC/CQ 7.1.2.6 to 8.0.1 upgrade on AIX

We got CC/CQ multisite environment hosted on AIX servers. Our environment includes 5 sites. Currently we are looking forward to upgrade to 8.0.1 version due to end of support of 7.1.2 version.

We are planning to perform upgrade without moving to VOBs schema 80 and feature level 7. Schema and feature level upgrade are planned to start after upgrading the server and clients to 8.0.1. Also planning to start the upgrade initially on one master site and upgrading the servers later on other sites.

I hope lots of people in this forum might have done the CC/CQ 8.0 upgrade . It would be a real help if you could share your experience and upgrade guide for us.

We are planning to upgrade CC/CQ from 7.1.2.6 to 8.0.1. As of now we are going to test it on our test environment.

Got few queries on the upgrade.

1. How to upgrade Rational License server to 8.1.3 ? In the prior 7.1.2.6 version, we used license setup script to install License Server, but now I believe we need to install using IBM Installation Manager. Need to know what are the things to be backed up from the existing version to upgrade to 8.1.3

2. I did check the SPCR reports and chatted with the CQ team and can confirm XP is not supported in CQ 8.0.1. Whether it works or not is another question so if you ran into problems that would be at your own risk. XP is out of support in a few months anyway so I would think it a bit risky to stay on that platform. However yes CTE is still supported on Windows XP with ClearCase 8.0.1. You could also use a CQ web server with a browser.

3. I can't speak to ClearQuest multisite as I've never used it but yes you can replicate between ClearCase sites running 7 and 8 _ONLY_ if the feature level is low enough that both sites support it. Generally speaking that is feature level 5 although you could go up to FL6 if you need synchronous request for mastership. So either you will use existing VOBs at feature level 5, or you will create VOBs at the CC 7 site, or if you create VOBs at the CC 8 site you must use the -flevel option so the feature level is not too high to replicate to CC 7 (eg -flevel 5).

I'm sure the WAS team has a guide somewhere but I'm not sure where offhand. Since WAS installs now with Installation Manager it's pretty simple assuming you have a gui (which you might not on AIX ... that could be a problem since you will either have to record a response file or see if the WAS support team has a sample). All you do is add the repositories for WAS including supplement & toolkit to get IHS, web plugin etc then pick the IHS port and install. I would recommend creating a new CCRC profile during the WAN Server portion of the CC install as it will do some auto-configuration for you. Then create a separate CQ profile if this is all on the same machine.

Thanks a ton for your update. In one site, we didn't support CCRC and CQ web. By default when we upgrade from 7.0 to 7.1.2.6, we installed CM server, but we didn't configured. Is it mandatory to install CCRC WAN Server for the 8.0.1. upgrade. If its not mandatory, does the 8.0.1 upgrade will uninstall the existing CM server.

Well, if you didn't configure (or use?) CM Server it was probably not helpful to install it as WebSphere can take up significant resources (like memory) when started. It is certainly not mandatory to install WAN Server for functional use of ClearCase or ClearQuest. The main reason to install it is if you have remote clients that are not able to use the full suite over a wide area network.

The version of WAS installed with CC/CQ 7.1 is tightly integrated into the installation of the product (unless you installed the profile into your own preexisting WebSphere instance which is not typical). The only version supported is WebSphere 6.1 and it must be uninstalled to upgrade to CC/CQ 8.x. If you are going to do a straight upgrade from 7.1 with CM Server to 8.x with WAN Server I would recommend these steps unless you have a reason to change them.

- modify the CC/CQ installs to remove the CM Server component. this will uninstall WAS and IHS

- update CC and CQ to the desired version

- install WAS 8 or 8.5

- modify the CC/CQ installs to add the WAN Server component. create new profiles unless you have reason to use an exising one (this is not common)

Yes, what you need to do is install CC/CQ 7.1.2.x via Installation Manager. Then you can download a desired version of Eclipse from eclipse.org and install the CTE 8.x plugin into it from your WAN server update site (eg http://server/ccrc/update).

Thanks a lot for your reply. You are confirming that its not possible to have CC/CQ 7.1.2..x native clients and CCRC 8.0.1.x client on the same machine. Am I right? If I need to install CCRC 8.0.1.x, I need to install standalone eclipse and use CCRC 8.0.1.x eclipse plugin to the standalone eclipse without using IBM IM.

On the other note, we are in the requirements gathering phase for the upgrade. It would be great if you can send me the IBM technote which says "CC/CQ 7.1.2.x native clients and CCRC8.0.1.x are not possible to be installed on the same machine".
